Four-time gold medalist Chris Hoy will mark his fourth Olympics by being Britain's flag bearer at the opening ceremony for the London Games.
The cyclist, who won the vote of the 542-strong British team, also carried the Union Jack in the closing ceremony in Beijing four years ago.
"To lead out your team at a home Olympics is truly a once-in-a-lifetime opportunity and one that that I can't wait to experience in just a few days time," Hoy said in a statement.
The honor comes after the 36-year-old Hoy was informed by British Cycling that he wouldn't be able defend all three of his track titles from 2008 at the London Olympics.
While he has a chance to again win gold medals in the keirin and team sprint, he will not be able to defend his individual sprint title.
